I just migrated my bilingual website to joomla 3.3.1 and I am discovering the tag feature, which is awesome! When I click on a tag displayed near the title of an article I am redirected to a page listing all the article with this tag. So far so good. But the problem is that there isn't any menu displayed on that component/tags page!

So I have been looking for a way to attach an itemid to a specific component page, but I didn't come close to a solution.

Are you sure you have the menu module assigned to all pages?

Thanks @Lodder! This does solve the issue, but it won't work because one of my menu item redirects to a part of the website where the menu-item is not the same. SO I have the menu module A and B and all the A menu item redirects toward pages with the A menu, except the menu item A-5 with redirects toward a page with the menu module B. And same thing for the menu B. Menaing that can't choose the option "assigned to all pages". Is there a way to assigned an itemid to a component page?

If you don't want this menu item visible, you can add it to a new menu. If you don't link this menu to a module, it will never show up on the site. But it will still be used for the SEF URLs. This way you can create nice URLs and even customise the view.

Thanks Bakual, this is the solution! You're right when I click on a tag I'm redirected to an address like component/tags/tag/science. So I did as you say, I created a new menu, added a new menu item (type tagged items), added the tag I want and assigned the menu module to this menu item... and voila! I preferred to choose tagged items rather than Compact list of tagged items because I prefer to get the intro text. The only downside is that I need to create one menu item per tag which is a lot of work. But anyway this is a better solution than the one selecting "on all pages" so thanks so much!
